摘　　要：建立裸花紫珠叶的HPLC指纹图谱，并同时测定其中10种成分的含量，为其质量控制及鉴定提供科学依据。采用Waters Sunfire C_18色谱柱（4．6mm×250mm，5μm），流动相乙腈（A）-0．1％甲酸（B），梯度洗脱，流速为1mL·min^-1，检测波长330nm，柱温30℃。运用中药色谱指纹图谱相似度评价系统（2012）进行分析。各批次裸花紫珠叶的指纹图谱相似度较高，10种成分分离度良好。裸花紫珠枝及同属4种紫珠与裸花紫珠叶对照图谱存在明显差异，定量分析条件通过方法学验证，平均加样回收率在96．0％～105．0％。所建立的定性、定量分析方法简便，准确度高，专属性强，可作为裸花紫珠鉴定及质量控制的依据。This study is to establish the HPLC fingerprint and determine eight components of Callicarpa nudiflora, and provide a scientific basis for the identification and quality control. The Waters sunfire Cls column（4. 6 mm × 250 ram, 5 μm） was used and the detection wavelength was 330 nm. The column temperature was 30 ℃ . The mobile phases were acetonitrile（A） and 0. 1% formic acid （B） eluting in a gradient program at a flow rate of 1.0 mL · min ^- 1. The chromatographic fingerprint similarity evaluation system for tradition Chinese medicine （2012） was used for analysis. C. nudiflora from different samples were of high similarity in fingerprint and the separation of ten components was good. There was an obvious difference between other samples and C. nudiflora leaves. In quanti- , regresslon（R 〉0. 0） tative analysis the ten components showed good regression （R^2 〉0.999 0）with linear ranges, and their recoveries were in the range of 96. 0%-105.0%. The established qualitative and quantitative methods are highly specific, simple and accurate, which can be used for the identification and quality control of C. nudiflora.
